Battery drain still happening... Completely stumped :( **UPDATE**

The siren is a control unit in its own right and communicates via Lin bus single wire. If the master unit cannot see it then it continually sends a signal looking for it and also let's it draw current from the battery to charge itself, until the voltage stored reaches a set level. With a faulty cell this cannot be achieved, hence the drain - continuous draw.

Ok so this is all kinda starting to make sense to me now...
I'm going to sound a bit stupid again though and im just trying to make sense of it all... how come my stereo fuse is active and using a huge amount of power? is it because of the master control unit is constantly sending that signal?
MJ:
That may be a separate issue entirely or it might be connected because one system is over ruling the other. The anti theft system has a high priority when it comes to power usage.

Having the new alarm fitted on Wednesday :)
Will be great if this sorts the issue. Everything is pointing to the siren but I'm tying not to get my hopes up.
Just did another check on the fuses and it's still draining. Same values as before so I hope they are still there when I take it to Ed on Wednesday!!

Did you see if you have an amplifier under the seat for fuse 18?

Yep. There was an amp there. Never noticed it before!
